I'm looking to establish a mobile broadband-powered network of laptops where I work (a school whose current net access is handcuffed by a restrictive filter). I've got 4 wifi-enabled laptops and I'd like to get them all connected to 3g internet; am I better off getting a 3g modem and then sending that signal out over 802.11 wireless? Or should I buy one usb modem for one laptop, and ICS it to the others? Or am I better off getting usb modems for each laptop- If so, do I need to pay separate service fees for every device?
I'm not sure what the best way to go is here. Any suggestions?
